Title: Performance monitoring of an atm switch
Inventor: LIU STEPHEN S
IPC: H04L12/56
Filed: 1997-03-27
Abstract: Management packets (36, 52, 54) are defined that are modified in the payload by each node (16, 18, 20; 24, 26, 28) along a virtual connection and are used to measure both end-to-end QoS and specific individual intermediate node performance parameters. Management packets (36, 52, 54) are implemented by defining entirely new packets or by modifying ATM OAM cells. Switches or routers for use as intermediate nodes are defined that modify the payload of the management packet (36, 52, 54) and locally measure packet delay and packet loss. An intermediate node measures and records the difference between the arrival and departure times of management packets (36, 52, 54) at that switch (31, 56) utilizing delay-stamp fields within the management packets (36, 52, 54) and either the switch internal routing header or timestamp fields (9) within the packet. At the endpoint of the virtual connection, delay-stamp fields (10) in the management packet (36, 52, 54) indicate individual node delays and the cumulative delay.

Inventor: DUCK GARY STEPHEN
IPC: G02B6/35
Filed: 1999-03-26
Abstract: The present invention relates to an expandable matrix optical switch module adapted to be used as an nxm switch singly or as a larger switch assembly comprised of multiple switch modules coupled together. The switch module includes arrays of input and output transfer waveguides, such as pigtail fiber connector ends, aligned with the input waveguide array and with the output waveguide array. Switch modules may be coupled together permitting a signal to be passed from a first into one or more additional switch modules, effectively increasing the number of input waveguides or output waveguides in a switch assembly. An existing switch module can be expanded as needed to accommodate increased needs. Larger switch arrays may be manufactured in smaller modular units an assembled to the custom requirements without significantly increasing production costs. Coupling is achieved using splice fiber techniques, fiber connectors, or direct lens to lens connection. Additional control means are necessary to coordinate software addressing and switching control.

Patent CA-2278750-A1 (CA)
Inventor: OSTENSEN JONNY
IPC: A61K49/22
Filed: 1998-01-22
Abstract: Ultrasound contrast agents comprising two or more types of gas-containing microparticles which differ in their susceptibility to ultrasonic pressure. Microparticle types having relatively low susceptibility to ultrasonic pressure provide a response to high acoustic energy in the near field where microparticle types with relatively high susceptibility tend to be inactivated through destruction. More highly susceptible microparticle types are effective in the lower acoustic energy environment of the far field, where lower susceptibility microparticle types will tend to exhibit little interaction.
